To all 'who/m, t may concern Be it known that I,- WILLIAM H. MoRGAN, a citizen of the United States, and a resident of Alliance, in thev county of Stark and State of Ohio, have invented certain new and useful Improvements in Railroad-Track Construction; and I do hereby declare the following to be a full, clear, and exact descriptio-nl of the invention, such as will enable Y others skilled in the art lto which it appertains to make and use the same.

My invention relates to an improvement in railroad track construction,v and is designed particularly as an improvement on the lconstruction disclosed in Patent No. 1,119,626 granted to me December 1, 1914.'v

In the patent above referred to the ties are shown as I-shape in cross section, with a base flange widerthan the top flange and inclined downwardly to form a housing in which the ballast will pack when tamped, and the chairs are composed Vof two side members or sections, connected by two yokes, the latter being integral with the side members and depending at oppositesides of the tie, the side members or sections being independent of'each other and connected by the yokes only, and each side member or section is provided with flanges adapted to be bent around the top flange of the tie for locking the chair to the tie. With the ties as vshown in the said patent, actual use has demonstrated that if one side edge be solidly supported on for instance a rock, and the other` edge resting on a softer andrm'ore yielding base, the load will be u nevenly distributed andV result in displacement and distortionof the'ties. Again, in the patent the chairs are of expensive' construction andare secured to the ties by bending 'sidefanges formed integral with the chair downwardly andy Vconsists in the Parts'and Combinati@ '0f parte as Will le@ .more lilly @Xrlaieef and pointedoutin theJ 531.2111115. A f 1,9 the .acomlnylig drawings, ,Fgere l is a view in perspectiveof a section of track embodying my invention; Fig-2isaview of a tie withI the chairs thereon; Fig. 3 is a view iny plan of one chair anda part of the tie; Fig. 4- is a view in cross section of the tie, and Fig. is a view in section of the tie and chair, showing the girders and rail carried bythechair.` `V` 6 represents a rolled or stamped metal tie having a flat'body memberfand a straight depending flange 7 at each edge. -The'tie maybe ofv any width and is preferablyl bent to produce the downwardly inclined rends as shown.

Securedto and resting directly on'the rflat body member of the tie are the'chairs'S,

each of which consists of a base 9 and up-v wardly projecting parallel side members Y10 cast integral. The base is of approximately the same' width as the tie, and veach chair is provided with a plurality of ears 11, the

vears of each side being inthe plane of thev ears at the opposite side so that the ears Aon the two sides vwill be in pairs.V The ears are each provided with a bolt hole, and the chair as a whole is'secured onthe upper face .of the tie 7 by the bolts 12, passing through 'the ears at one'side ofthe chair,

through the depending flanges 7 of the tie and through the earson vthe other side lof the chair, and are secured bythe nuts 13.

lThe chair is providedv centrally withv'an .integral centrally located lug or boss 14 ydependin'gfrom the lower yface ofthe base thereof and resting. within a` similarly shaped opening in the body of the tie. The boss assists in holding lthe chairs in the pro'per'relative position'to maintain the gage of the' track and also to take care of the side stresses, thus relieving the bolts from 'all shearing strains. Y 'i The 'SdfeS l0 "0f the Chair are reinforced by the'integral 'ribs 15 and'l, one of each to each lside member'lOQthe ribs 15a which are diagonally disposed to each other being enlarged at their juncture with the side members and provided with sockets extend# ing approximately i throughout their depth to receive the wood' plugs v16. The sockets containing the wood plugs are formed partly in' the Sidel members A10 and-partly in the flenforcine ribs aS ClearlyA Shown in Figs.

3' and-.55 's0 that when ,theerdeirs 17V are Placed' in Position, their rail Supporting ags lS will 'eveflap'the Wood plugsand Prei'elrlt'any ,tefilelly .0f the lattr t0' dis:

placement. The ribs 15 and 15u project above the side members 10 and form stops 10a which operate to prevent any lateral movement of the girdersfor lrails, and the top surfaces 19 of the side members are beveled to conform to, and form solid and substantial supports for the rail carrying flange `of the girder 17 The girders 17 are preferably old steel 'rail-s, placed head down between the side members l() of the chair, and with their base flanges 18 resting on the top surfaces 19 of the side members l0. Any other form of girders will answer the purpose, but I prefer old rails on account of their cheapness and also because ofthe superior quality of metal from which they are made. Y

The girders 17 are approximately the depth of the side members 10 of the chair so as to substantially fill the space between said side members, and are suspended from, and wholly supported by the top surfaces of the side members, the lower edges of the girders being above and not in contact with the bases 9 of the chairs. These girders support the rails 20 throughout the length of the latter, except possibly at the switches, l

and are arranged to break joints with the rails, so that a joint in the rails and a joint in the girders will not come between the same ties.

The ends of the girders may, if desired, be connected by fish plates, but this is not essential. The ends of the rails are however connected in the usual manner, and the connected rails and the girders carrying the latter, are 'restrained against vertical or tilting displacement by the spikes 21 driven into the wood plugs 16, the heads 22 of said spikes overhanging, but preferably not in contact with the base flanges of the rails, thus leaving the rails and girders loosely seated on the chairs and free to move lengthwise without opposition and also free t0 move vertically a limited distance.

There is theoretically no tendency of the rails to tip, but as the heads of the spikes overhang the base flanges of the rails and are only removed therefrom a limited distance, tipping to anything like a dangerous extent would be prevented by the spikes.

In order to gage the rails and hold them in proper relative position, I insert gage bars 28 between the base flange of the rail 2O and the stops 10a as shown in Fig. 5. These gage bars project above the outer edges of the base flange of the rail, and

v form a solid seat for the heads of the spikes thus preventing the heads of the spikes from coming in contact with the rail. By using gage bars of various widths, the rails can be gaged to a nicety and when the latter are worn'to such an extent as to require readjustment, it can be done by simply removing the gage bars and substituting thinner ones at the inner sides of the rails and thicker ones at the outer sides.

lVith the con-struction above described the rails are supported throughout their entire length hence the load is distributed on and f between all the ties, and over the entire bearing surface of each tie. Again, a lighter rail can do the work of a much heavier one that is supported at intervals only, hence smaller rails can be safely used with the heavy rolling stock that is now coming-into use, and which could not be used if supported only at intervals.

By using ties of the form shown, and chairs composed of a continuous base and two integral side members, the base being approximately the width of the widest part of the tie, and the side members as long as the tie is wide, I distribute the rolling load uniformly over the whole tie, so there is less tendency for the ties to tilt if not uniformly supported in the ballast, and also distribute the load over a greater number of ties, the girders forming in effect a bridge for carrying the load over and onto several ties.

It is evident that many slight changes might be 'resorted to in the relative arrangement of the parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact construction and arrangement of parts shown and described, but

I-Iaving fully described' my invention what I claim as new and desire to secure by Letters-Patent, is

1. In railroad track construction, the combination of a wrought metal tie having a fiat upper face and depending edge flanges, and a chair secured to said tie, the said chair comprising a single flat base member approximately the width of the tie and two side members extending throughout the width of the base member, and integral with the latter, the upper edges of the side members forming supporting shoulders.

2. In railroad track construction, the combination of a wrought metal tie and a chair secured to said tie the said chair comprising a single flat base member to rest on the tie and approximately the width of the latter, and two upwardly projecting side members integral with the base member, the upper edges of the side members forming rail supports.

. 3. In railroad track construction, the combination of a metal tie consisting of a straight flat section and depending edge flanges, a chair on said tie, the said chair comprising a flat base member having depending ears adapted t0 overhang the edge flanges of the tie, and upwardly projecting side members integral with the base member and. extending throughout the width of the latter the upper edges of the side members forming rail supports, and bolts passing through said ears and edge flanges and locking the chair to the tie.

4. In railroad track construction, the combination of a metal tie having an opening in its top surface, and a rail supporting chair secured to said tie, the said chair comprising a fiat base member having a depending boss to rest within the opening in the tie, and ears to overhang the sides of the tie, and two upwardly projecting rail carrying members integral with the base member, and means passing through the ears and into the tie for locking the chair to the latter.
